DRIVE FOR HEIGHT-MOVED rJLOCKS,

Application filed Qctcber 2 1, 1921.

T 0 all whom it may concern:

Be it known that I, TOBIAS BliUnRLn, a citizen of the German Republic, residing at St. Georgen, Germany, have invented certain new and useful Improvements in Drives for Weight-Moved Clocks, of which the following is a specification.

With spring-moved clocks it has already become known to drive by means of the spring barrel the clockwork as well as the striking mechanism. For weight-moved clocks it has however not yet been possible to use the weight barrel for the two purposes.

This object has been attained by the pres ent invention according to which an auxiliary axle is arranged in the weight barrel keyed upon its shaft, said auxiliary axle carrying two drive wheels outside the side walls of the barrel, one of said wheels meshing with the inner teeth of a drive wheel loosely mounted upon the shaft of the barrel (designed for instance to drive the clockwork), the other wheel meshing with a toothed wheel loosely mounted upon the shaft of the barrel (designed for instance to drive the striking mechanism).

This arrangement permits to drive both mechanisms either simultaneously or separately from the weight barrel.

In order that the invention may be clearly understood, I shall proceed to describe the same with reference to the form of construe tion shown by way of example on the accompanying drawing, wherein Fig. 1 shows the weight barrel in a longitndinal section.

Fig. 2 is a side elevation of Fig. 1.

The weight barrel a is keyed upon the shaft 6. In the side walls 0 of the barrel a small axle cl is mounted so that it can freely revolve. Upon the ends of this axle (Z, outside the side walls 0, a pinion e and a pinion f are keyed. The pinion meshes with the inner teeth 9 of a toothed wheel 7L loosely mounted upon the shaft 6 of the barrel, said toothed wheel serving for instance to drive the clockwork mechanism. The pinion c is in gear with a toothed wheel fixed to a ratchet wheel k and loosely mounted with said ratchet upon the shaft 7). The pawl m for the ratchet 7c is pivoted upon a disk a loosely mounted upon the shaft 6, and designed to act upon a driver 39 of a Specification of Letters Patent.

toothed wheel 0 which is loosely mounted on shaft 7). The driver p is fixed upon a ring q which is inserted in the toothed wheel 0, said toothed wheel serving for instance to operate the striking mechanism. The parts loosely mounted upon the shaft Z) are secured in their positions by two disks s which are secured themselves by pins t, u.

The device operates differently according to whether neither the clockwork nor the striking mechanism are braked against the revolving motion transmitted from the shaft a of the barrel through the action of the weight or whether one of said mechanisms is braked. In the first case the barrel a revolves by means of the pinions e, which however are not revolved individually, all the driving parts of the two mechanisms. )Vhen the clockwork mechanism is. braked the pinion f rolls along the inner teeth g of the driving wheel h for the clockwork mechanism. The individual revolving movement of the axle (Z which is thus produced operates the striking mechanism by means of the pinion e. If however the striking mechanism or its driving wheel 0 is braked only the clockwork mechanism is operated through the intermediary of pinion f and the inner teeth g, owing to the revolving of the pinion caused by toothed wheel 2'. The two mechanisms can therefore be operated either simultaneously or separately.

A. separate drive could be provided for the striking mechanism or for the striking mechanisms, in which case the weight barrel for the clockwork mechanism could be used as auxiliary drive for the striking mechanism.

I claim 1. An improved drive for weight-moved clocks comprising in combination with the weight-moved barrel, the clockwork mecha nism and another mechanism (for instance a striking mechanism) and means for operating said two mechanisms from said weight-barrel.

2. An improved drive for weight-moved clocks comprising in combination with the weightmoved barrel, the clockwork mechanism and another mechanism (for instance striking mechanism), a small axle revolubly mounted in said weight-barrel so that its ends project over said barrel, two pinions loosely mounted one upon each projecting end of said axle, a toothed Wheel loosely mounted upon the barrel shaftfor driving the clockwork mechanism having inner teeth with which one of said pinions is in gear a second toothed wheelloosely mounted upon the shaft of the Weight-barrel in gear With the other pinion, a driving Wheel for the second mechanism, and means for revolving
